Sarah has been a mentor since I first visited UCSD last year as a prospective student. She exudes warmth and friendliness and goes out of her way to make sure that people feel welcome and comfortable in the department. Although Sarah is always busy working herself, she always finds time for others. Whether it is a quick conversation on "gmail chat" to inquire about a worrisome away message, a lunch to talk through first-year grad school angst, or advice and suggestions about living in the city of San Diego, Sarah is the first person I turn to for help! She is extremely committed to our department and goes above and beyond to make sure that things function smoothly. She is an exceptional role model and friend.
